Patent CA-2431929-A1 (CA)
Title: Devices for sealing openings through tissue and apparatus for delivering them
Inventor: GINN RICHARD S
IPC: A61B17/00
Filed: 2001-12-11
Abstract: An apparatus for sealing a passage through tissue includes an elongate shaft and a cylindrical plug disposed on a distal end of the shaft, the plug including a helical thread on its outer surface. Intestinal submucosa may be secured to the plus, e.g., in a cavity in its distal end, that may be delivered into the passage. Alternatively, the plug may be formed from a bioabsorbable material and may be released from the shaft within the passage.  The plug is threaded into the passage, thereby engaging the tissue to seal the passage. The shaft is rotated until it engages a blood vessel within the tissue while monitoring blood flow through the vessel. The shaft is rotated to thread the plug into the passage until blood flow ceases through the vessel, whereupon rotation of the shaft is reversed to back the plug until blood flow through the vessel resumes.

Inventor: LYNCH ROBERT LEROY
IPC: H04L12/26
Filed: 2002-07-23
Abstract: Packet communication systems, or networks, are commonly used for the conveyance of information for data applications. The receive rate of incoming packets varies as congestion in the network causes variation in the amount of time for a packet to traverse the network before being placed into the JAB (Jitter Absorption Buffer). The disclosure contains methods for calculating a real time measurement of PDV (Packet Delay Variation). This real time measurement is useful as a metric on the quality of the service provided by the network or as a trigger for dynamic adjustment of the operation of equipment to optimize for current network conditions. More specifically, the disclosure includes a method that uses variations in the buffer depth of the JAB to measure PDV.  This abstract is provided as a tool for those searching for patents, and not as a limitation on the scope of the claims.

Title: Pass through valve and stab tool
Inventor: HAYES KIRBY
IPC: F04B47/02
Filed: 2004-03-11
Abstract: A method and system allows periodic access the wrong way through one or more one-way valves installed in a fluid flow stream. Fluid can flow through the bypassed valves or through the tools used to bypass the valves such as those of a reciprocating production pump. A stab tool cooperates with a valve to unseat a ball from a ball seat so as to bypass the ball and pass through the ball seat. The stab tool can be conveyed by tubing for discharge of fluid through ports in the stab tool. In another aspect of the invention, a rod installed within a pump between a reciprocating uphole valve and a downhole valve is arranged so that when the pump is closed, the stab tool at the rod's bwer end passes through the downhole valve and a projection at the rod's upper end passed though the uphole valve the pump is partially closed. Fluid can be pumped in reverse through the pump fluidize debris.

Title: Wild game call
Inventor: ADY DANIEL D
IPC: A01M31/00
Filed: 2004-07-19
Abstract: A game call includes a mouthpiece having a plurality of vibrating reed areas, and/or a mouthpiece that is adjustable relative to the housing, to produce unusual and complex sounds that are very much like wild game sounds. The plurality of reed areas may be two areas of a single tubular reed vibrating on different areas of the mouthpiece, and, preferably, vibrating on opposite sides of the mouthpiece. The opposite sides of the mouthpiece may include surface contours, including indentures, curvatures, or apertures, which cooperate with the vibrating reed and/or subsequently affect the air waves created by the vibrating reed. The mouthpiece cooperates with a housing, so that air from the user's mouth travels across the reed areas, creating vibrations in the air, which air vibrations travel into the housing resonating chamber, and out to the surrounding area. Modifying the reed, number and shape of the contours, indentures, and/or apertures, and/or the position of the mouthpiece relative to the resonating chamber, affects the sounds produced, allowing the mouthpiece to be adapted into calls for a variety of wild game species.
